Basic concepts

It is useful to understand the several layers involved in the Odoo architecture, and the role of each type of component we will use. So we will have a pragmatic overview of the Odoo application architecture, with a focus on helping application development by decomposing work into several components.

Also, Odoo publishes two different product editions, community and enterprise, and regularly releases new versions for both. It is important to understand the differences we can expect between the editions, and what a new major release can mean for our development and deployment. For this, we have an overview of the differences between CE and EE, and on the Odoo major version stability policy.

Let's start looking at the Odoo application architecture.
